Application March 14,

. 1 Claim.

My invention relates to a new and useful improvement in a reed hook adapted for use in threading reeds of looms with warp threads.

It is an object of the present invention to V provide a device of this class which will be simple in structure, economical of manufacture, durable in construction, and highly efficient in use.

Another object of the invention is the provision of a reed hook in which a minimum amount of movement of the thread engaging blade will be necessary for performing the operation of threading the reed.

Another object of the invention is the prol5 vision of a reed hook having a transferring mechanism whereby the thread engaging blade may be transferred easily and quickly from one side of a reed dent to the other without subjecting the transferring mechanism to strain incident to the drawing of the warp thread through the reed.

Another object of the invention is the provision of means for adjusting the transferring mechanism so that the device may be used on various sized reeds and with dents varying in width and thickness, and so that the mechanism may be adjusted to suit the individual using the dev1ce.

Other objects will appearhereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

'Ihe invention will be best understood by a reference to the accompanying drawing, which forms a part of this specification, and in which,

Fig. -1 is a perspective view of the invention, showing it in use.

Fig. 2 is a vertical, central, sectional view of the invention showing it in one position.

Fig. 3 is a side elevational View of the invention, showing it in a progressive position of operation relative to the position shown in Fig. 2.

Fig. 4 is a central, sectional View of the invention, showing the device in a further progressed position of operation relative to the position shown in Fig. 3.

Fig. 5 is a perspective view of the invention, showing it in separated relation, with the blade shown in fragment.

Y Fig. 6 is a perspective view of a modified form of a portion of the device.

The invention is adapted for use in drawing Warp threads 9 through the spaces I0 between the dents I I of a loom reed. The invention comprises a blade I2 formed preferably from sheet 1934, seran No. 715,445

steel vor other suitable metal, and provided with a handle I3 whereby the same may be gripped. As indicated, this' blade is provided on one of its edges with the thread receiving notches I4 and I5. Projecting outwardly from opposite sides of the blade adjacent one end are bosses I6 and I'I, these bosses being located inwardly of the end which israngularly turned as at I8.

A piece of spring metal is doubled upon itself to provide a loop so as toy form the legs I9 and 29. One of these legs is flared outwardly at its end as at 2I from the other leg, and the otherY leg at its free end is angularly turned as at 22 toward the outwardly flared leg. In operation, the loop is positioned over the end of the blade so as to straddle the same, and the bosses I 6 and I1 engage in openings 23 and 24 formed in the legs I9 and 20. The inwardly turned end 22 of the leg 2D engages in a holeor recess 25 formed in one face of the blade I2, and the angularly turned end I8 of the blade engages in a hole or recess 26 formed in the inner face of the leg I9. Extended through openings 21 and 28 formed in the legs 20 and I9, respectively, is a bolt 29 provided with the nut 30. By screwing the nut 30 onto the bolt I2, the tension of the loop may be increased.

In operation, the blade I2 is thrust through the reed so as to project through .o-ne of the spaces II). The transferring mechanism is then positioned on the blade as shown in Fig. 1 and Fig. 2. The individual threadsY are successively engaged in one of the notches I3 or I4, and the blade I2 is then drawn downwardly through the reed so as to pull the thread through one of the spaces I0. As shown in Fig. 2, the blade I2 is projected between the dents A and B. As the downward movement continues, the thread 9 is drawn through the space C. As the downward movement progresses, the flared end 2| will ride over the dent B so as to engage in the space D. As the downward movement continues, the turned end I 8 of the blade Will be forced out of the rec-ess 26 until the end of the blade has ridden off of the dent B, upon which, the end of the blade will again snap into the recess 26, as shown in Fig. 4.

An upward movement of the'blade will cause the leg 22 to spring outwardly so as to disengage from the boss I'I, and When the leg rises above the upper edge of the dent, it will again snap into its former position, and the blade I2 will lthus be engaged in the space D for engaging a succeeding thread and pulling it through this space. Thus it is apparent that the device may quickly effected with a minimum eifort on the Y part of the operator.

In Fig. 6 I have shown a slightly modified form of transferring mechanism in which the legs I9' and 20 are formed from separate pieces and provided with the openings 23', 24', 21 and 28'. The ends 2| and 22 are angularly turned as described for the form shown in the rest ofthe views. These legs I9 and 20' are welded, or otherwise suitably secured, to a spacing block 35.

This construction permits a slightly increased tension of the legs in clamping relation on the blade l2.

While I have illustrated and described the preferred forms of construction of my invention, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

In a reed hook of the class described, a transferring mechanism comprising a pair of resilient legs engageable with each other, adjacent one of their ends, the opposite ends thereof being spaced apart; and a threaded member projecting through the spaced apart ends of said legs and adapted upon threaded movement for adjusting the tension of said legs at their engaging ends.
